Josie was born prematurely Dec. 10 at a gestational age of just 25 weeks and weighing only 1 lb. 6 oz. The preemie was released from the hospital on April 6 but returned two days later due to "minor stomach issues," her parents told UsMagazine.com.

Josie has now been released after doctors finally discovered the cause of her condition.

"Her digestive issues have been linked to lactose intolerance," says her physician, Dr. Robert Arrington. "We are happy that she is doing so well and fully expect her to continue to thrive. Today, as she's leaving, she looks like a full-term baby." She now weighs 7 lbs. 6 oz.

Josie's homecoming will be featured in the premiere of "19 Kids and Counting" on Aug. 10 at 9 p.m.
